Labahitha nicobarensis ( Tikader, 1977) comb. nov.

Filistata nicobarensis Tikader, 1977: 160 , fig. 1A–C. Holotype female and paratype male and females from India, Car Nicobar, 8 Mar. 1970, B.K. Tikader leg., deposited in the National Collection, Zoological Survey of India, Calcutta or in the Zoological Survey of India, Poona, not examined .

Pritha nicobarensis – Patel 1978: 186.

Notes

We have not examined the type specimens, but the teardrop-shaped bulb with a keel-like paraembolic lamina figured in the original description ( Tikader 1977: fig. 1C) clearly indicates this species belongs to Labahitha . We provided a tentative diagnosis and consider this species as valid, but re-examination of the type material would be desirable to confirm its validity. It should be noted that there is an older available name based on specimens also from the Nicobar islands, Filistata insularis Thorell, 1891 , which we were unable to examine; it is not unlikely that they could be synonyms.

Diagnosis

Males are similar to those of L. oonopiformis , L. ryukyuensis and L. garciai by the teardrop-shaped bulb with a keel-shaped paraembolic lamina. They differ from all these species by the shorter, more straight and robust embolus ( Tikader 1977: fig. 1c). The female genitalia has never been illustrated and thus we are unable to provide a diagnosis for the female at this time.

Description

See Tikader (1977).

Distribution

India, Andaman and Nicobar islands ( Fig. 1B ).
